The correct option is "2. Permissions." In JIRA's administration settings, permissions are used to control access to various functionalities and features within a project. By configuring permissions, administrators can grant specific rights to groups of users, such as viewing, editing, or administering issues. Navigating to the permissions section allows administrators to manage access control efficiently.

In Scrum methodology, tasks are broken down into smaller units called "Tasks." This allows for better management and tracking of progress during the sprint.

Regularly testing the backup restoration process ensures that JIRA administrators can confidently recover data in case of emergencies. This practice helps identify any potential issues with the backup or recovery procedures and ensures the reliability of the backup system.

Optimizing workflow performance for large teams and projects involves simplifying the workflow to reduce unnecessary complexity and transitions. This helps in streamlining processes, improving efficiency, and minimizing the risk of errors or delays, especially in environments with a high volume of users and issues.

The purpose of the Daily Stand-up meeting is to synchronize the team's activities, identify any impediments or roadblocks, and ensure that everyone is on track towards meeting the sprint goal. It's a short, time-boxed meeting where each team member provides updates on their progress, discusses any challenges they're facing, and collaborates on solutions.

Issue type schemes in JIRA enable administrators to define which types of issues are available within each project. By configuring these schemes, teams can ensure that only relevant issue types are available, streamlining the project's workflow and maintaining consistency across different projects. Understanding and managing issue type schemes are crucial aspects of customizing JIRA to suit specific project needs.

Backlog grooming or refinement meetings in Agile serve the purpose of reviewing and prioritizing backlog items. During these meetings, the team collaborates to refine user stories, ensuring they are clear, feasible, and appropriately prioritized for upcoming sprints. This process helps maintain a well-groomed backlog, which enhances the team's ability to plan and execute iterations effectively, ultimately leading to successful product increments.

In JIRA, you can control work in progress (WIP) limits on a Kanban board by setting WIP limits for each column. These limits help teams maintain a manageable workload and prevent bottlenecks in the workflow. By defining WIP limits, teams can focus on completing tasks rather than starting new ones, which improves overall efficiency and delivery speed.

Project administrators can configure Assignee Rules to automatically assign issues to specific users or groups based on predefined criteria. This helps streamline the process by ensuring the right people are responsible for handling each issue.

In Agile methodology, the Product Owner is responsible for prioritizing the product backlog, ensuring that the team works on the most valuable tasks first. This role involves collaborating with stakeholders to understand their needs and conveying those needs to the development team through user stories.

When designing workflows for compliance, it's crucial to document and audit all workflows for traceability. Documenting workflows helps ensure that the workflow accurately reflects the compliance requirements, and auditing ensures that the workflow is followed correctly. Transitions represent the different states an issue can move through in a workflow. Screens represent the user interface elements for capturing or displaying information. Projects represent collections of issues.

The main difference between Agile and Waterfall methodologies lies in their approach to project management. Agile emphasizes flexibility and iterative development, allowing for changes and adaptations throughout the project, whereas Waterfall follows a sequential approach with distinct phases, making changes more difficult once a phase is complete.
